ALL Nuclear Physics Explained SIMPLY

[@douglasboyle6544]

I've known all of these things since I was in high school essentially (thirty years ago) but I still watch channels like yours because I can still always learn something or get some nuance. And this time was no different, I never completely grasped why the Strong force is eventually overcome in large nuclei by the EM force, I never caught on to the additive effect of the repulsion of the EM charge of the protons. Once again, you've taught me something and made it very much worth my while to tune in, thanks :)

Arvin is a brilliant teacher, we need more like him to teach and explain mathematics, science and engineering, with the hope the many young (and not so young) decide to study these subjects. Thank you, Sir.

im the outlier bruh im 13

[@zack_120]

6:35 - for easier memory, alpha particles/decay are emissions of helium nuclei, beta particles are electrons released from neutron decay into protons, and gamma particles are mass-less, high energy photons.

[@andreasg7543]

Danke!

[@ArvinAsh]

Thanks so much.

[@BenjaminGSlade]

Thanks!

[@ArvinAsh]

many thanks!

[@shaunhayward]

I love your videos. I barely have a high school education but find it tremendously interesting. You present things to very well. Thank you so much!

[@ArvinAsh]

Glad you like them!

[@PMA65537]

I spent 7 years in the nuclear industry and it doesn't make parties interesting. It just means people who think they know more than you try to convince you your safety work is all mistaken. And that's after a week of work when you want some time off.

[@hisss]

_Obviously_ a layman who's watched a KZbin vid or two knows more than you, silly professional! I work in IT. I feel your pain.

[@AnthonyGoodley]

Many people are intimidated by someone who is much smarter than they are when it is made obvious. I suspect that it's an ego thing.

[@steveDC51]

Just 7 years - you had barely started.

[@kurtdorr]

You sound like a barrel of laughs at parties. You always so fun?

[@thomasgreene5750]

I spent more than 40 years in the industry. I learned in grad school that the general population consists of four groups of people. The first is a relatively small group in the "Amen Choir", and they are with you on philosophical grounds. A second, larger group is opposed on philosophical grounds, and nothing you say will change their minds. The third and largest group do not think much, do not care much, and if they are swayed at all, it is by whatever they last heard that they can remember. The last and smallest group contain people who know how to think critically and care enough to try to separate fact from fiction. This last group is the only one worth engaging with. You are wasting your time with the rest.

[@paulc96]

Thanks (again) Arvin for another excellent video, explained clearly. Love the Velcro example for the SNF - I have seen it demonstrated once before, with Velcro glued onto 2 bar magnets, then the two same poles being forced together. Please keep them coming. Best wishes from West Wales, UK.

[@jaredhamilton6913]

The breadth of your value as a teacher can not be overstated. Whether I’m revisiting things that are familiar, or those that I am still learning, you are the pulsing magnetar from which the field of information propagates into minds such as mine which, as nature would have it, responds to the field in a different way than the preponderance of others. So on behalf of all of those like myself, thank you for your unique attributes that bestow the force carriers of the field such that our minds may be bombarded by the quantum effects of the Arvinton field.

[@SSS-hr4ey]

Loved the video Arvin, best utilisation of 12 minutes I’ve experienced all week. Thanks

[@andreyassa7638]

This video is amazing! To be conveniently ushered through all nuclear physics in such an educational and entertaining way, was quite impressive. I'm really grateful for you, producing always such enthralling content. On top you are such a kind and likeable person in my opinion, thanks a lot for all your effort!

[@samorgan5361]

This is a treasure trove of a video, thank you!

[@anthonycarbone3826]

The video was very informative and explained some concepts that needed explaining so understanding could take place. Much of what was said was taken for granted like it needed no explanation but Arvin Ash drilled down into the details missing from any physic lesson I have ever attended. The funny part is I did not even realize the details needed further explanation!!!

[@Rationalific]

You give some of the very best scientific explanations out there! This relatively short video explained a ton and was super-entertaining as well! Keep up the great work!

[@Raintiger88]

Wow. . this is hands down the best explanations I've seen. Thanks for expanding my understanding!

[@mixerD1-]

Thank you Arvin... thoroughly enjoyed this.☺️

[@kayodave7191]

I find a good way to describe how ridiculously more powerful thermonuclear bombs are (hydrogen bombs) by pointing out, as Arvin says at 11:19, that a hydrogen bomb uses a fission bomb (i.e. the type of bombs used in WWII) as its TRIGGER. Imagine how much force it takes to squeeze the trigger of a gun vs how much damage a gun can do. That’s the kind of separation between the energy output of an atomic bomb vs a hydrogen bomb. Always awe inspiring and terrifying to think about.

[@claudiorassouli1240]

Never knew that gamma radiation is the byproduct of the protons and neutron realigning itself in the nucleus. Another great video where I learn just a couple new things. Thank you for breaking it down for me.

[@An_Attempt]

Beautiful, you have answered questions that I have had for years.

[@randywa]

Dangerously interesting is a phrase I have never heard before. I love it

[@swordoftemple]

This was the best explanation of the subject, thank you.

[@RM-pr4cw]

Love this channel! Wish it was around when I was studying university level physics in the 90s

[@andycopeland7051]

"Dangerously interesting at your next dinner party." Niiiiiiiice

[@jaybruce593]

Arvin has always been a top tier science educator, but his latest content has been knocking it out of the ball park, and this particular video goes as far as knocking it into another league, simply outstanding work my friend o7

[@WSmith_1984]

Modern science isn't correct..... All energy and matter in one simple explanation.... here goes... First we have a radio wave all the way to gamma waves which in turn create hydrogen then from there everything is basically a compound of hydrogen and will decay back to hydrogen before turning back to gamma waves..... There are no free moving electrons within matter.... I use this analogy to simplify it in my mind..... imagine a line of people standing a mile long (each person represents a copper atom in a wire) the first person starts a Mexican wave at one end ( the source ) , as the information propagates along the line ( by exciting each atoms magnetic field ) you would see an continuous wave of the peoples arms transferring the charge/information back and forth but the atoms and electrons don't actually move at all..... Think about it, from the source where electricity is "generated" to the ultimate end use, there's various breaks in chain of that electricity, it goes through controllers, transformers, all sort of components.... the transmission happens because of the magnetic field strength of the atoms in the wire being increased and decreased, not because of an actual "electron" flowing anywhere....

[@AnthonyGoodley]

Thanks for yet another educational video Arvin. I wish you would have touched upon how a Neutron bomb works. In many ways that'd be the deadliest type of Nuclear Bomb. Most people have never heard of it. Yet it is more likely to be used than any other type of Nuclear Bomb if it's being used strategically.

[@Quadflash]

Wow! Dr. Ash, I have some conceptual understanding of the information you've presented here. As I watch your video (repeatedly), I'm awed by the flow and completeness of the information. For background, I've been fascinated by nuclear and quantum physics for years -- lots of classes and reading on these subjects. (I'm certainly not expert) I'm wondering what someone with little prior knowledge would find in this video? Wondering if many of your viewers would find a little pre-work useful before becoming seriously interesting people? 🌞

[@ETAonTheEUC]

I’ve been going on an information-binging spree concerning atomic energy, and this is the best and most conclusive video I’ve seen. Super cool stuff. Super interesting

[@WNCGBS]

Excellent tutorial, Arvin. Will share with my Physics students. Well done!

[@ArvinAsh]

That's wonderful! Thanks for spreading scientific knowledge.

[@UffeHellum]

Always brilliant, but this time you really managed to put scary technical terms into simple birds-eye explanations. A great thank you, for dumbing it down enough to be pleasant for those 99% of us who are a little bit phobic of complicated words and math! Learning should be pleasant, not scary!

[@ArvinAsh]

Exactly my sentiments! Glad you enjoyed it.

[@aliawan9595]

Amazing and brilliant.. You really explain difficult concepts so simply and make them look easy... Kudos 👏 💐

[@Good13man]

I learned so much from this video. Thank you!!

[@rwarren58]

All concepts were explained so clearly I don’t have any questions, just a certain smugness due to new knowledge.

[@gsmith8098]

Great episode Arvin 👍 Clear precise and informative. If quantum mechanics was as easy to understand, I'd be a physicist 🤣😜

[@hardboieggz]

This is amazing, with these concepts I finally have a grasp of how nuclear fission works and how this generates energy

[@J_i_m_]

@3:42 I'm so glad that you consider Bismuth as unstable and thus radioactive. Many do not agree on this, including ChatGPT (and of course they are wrong 😁)

[@ArvinAsh]

It is pretty stable, but not completely, as you know. Half life is pretty long.

Why doesn't the fission chain reaction continue forever? Are lighter elements not destabilized by the neutrons entering their nucleus?

Love your work Arvin. I put you right there with Sabine, Nick(Science Asylum) and Brian Greene as my favourite science communicators. I feel smarter for having watched any of your videos.

[@simonmaverick9201]

How can you compare him with Sabine????? You obviously have a lot to learn.

[@connecticutaggie]

How small could you make a Fusion Bomb? Could you make one small enough that you could harness the energy?

[@ArvinAsh]

100+ million degrees Celsius needs a lot of energy to be achieved. This is why powerful lasers are used in current fusion experiments. I am not sure how small a hydrogen bomb can go, but without lasers, I don't think you can achieve those temperatures without exploding a fission bomb.

[@connecticutaggie]

@@ArvinAsh No, I mean keep the fission bomb, just contain it.

[@yourguard4]

@@connecticutaggie There is a limit, how small you can make a fission bomb. You need a critical mass of radioactive material (for example ~ 50 kg uran or ~10 kg plutonium). Even the smallest atom bomb is still about the half of the power of the hiroshima bomb. Good luck by trying to contain this :P

[@alfadog67]

Ah, the "learning" dopamine just keeps coming. Thanks, Professor Ash! I noticed the nuclei seem to have random nucleons positioned throughout, but I wonder, are they in superposition while floating around the nucleus, rather than the little balls that we perceive?

[@SernasHeptaDimesionalSpace]

1:36 - The nuclei of atoms are made up of protons and neutrons - The way i see it is that neutrons are as well protons and electrons - neutrons should be found at the equator or disc of any system(atoms, planets, stars etc) so there are protons working as neutrons and electrons working as well like neutrons. Likeor same charges repeal and as well cancel each other - any system or part with same charges wont be found.

I knew all of this when I was only 2

[@001firebrand]

Just brilliant, our honored scientist, Dr. Ash! 💖

[@gerhardwiesinger]

Nice, some questions: What happens to the Alpha particle hitting e.g. the paper (or any other object)? What happens to the Beta particle hitting e.g. the aluminium foil (or any other object)? What happens to the gamma radiation hitting some other object? Will the object hit by Alpha, Beta particles or gamma radiation also get "radioactive"?

[@ArvinAsh]

Great question! Alpha particle in a typical nuclear decay does not have a whole lot of energy, and since it's heavy, it has a short range. It may ionize atoms as it passes by them by ripping their electrons away. And it will then typically bounce off an object, much the same way that a helium atom would. A beta particle will simply lose its energy in the atomic structure of the object that it hits, contributing a little bit to the thermal energy of the object. A gamma particle would need to pretty much hit the nucleus of an atom to be stopped, that's why it penetrates so deeply.

[@CraftyF0X]

Ultimatelly, the alpha particle becomes a helium-4 after sufficiently slowing down and getting 2 electron for itself. (this process provides the current helium-4 stock of Earth) The beta particle is just an electron and after losing its kinetic energy due to scattering or bremsthrelung it just hangs around depending on what absorbed it mostly as the part of the enviroment as an ion or in a metal just as member of the electron sea. Gamma radiation may cause a photo electric effect with an atom's electron (kicking it out of the atom) participate in pair production (when it interacts with a nucleus but this require certain high energy levels) also may Compton scatters from an electron and lose energy to it. A sufficiently high energy gamma ray can also induce photo fission in a suitable nucleus. Now as I think about it really depends on the gamma energy level and the material it meets, it even can cause neutron emission when it radiates Be-9.

[@alexdemoura9972]

Dear Arvin, thanks for the explanation - I really appreciated it. I have a (stupid) question since I just got my "DINPA" degree - 10 minutes away from going to my Nuclear Physicist one: If the Neutron decays into a Proton + Electron + Antineutrino - and the atom gets a new positive charge - shouldn't the (new) free Electron fit a position in the electrosphere and orbit the nucleus of the very same atom? To keep the atom electromagnetically balanced? So why is there beta radiation (made by Electrons)? Why not only Antineutrinos radiation? Is there too much energy (too much speed of a particle) in Neutron decay, and the atom can't keep the Electron to itself?

[@ArvinAsh]

Great question! Correct that It is typically carrying too much to be captured. However, as you know the universe prefers to have charge neutrality. This does happen because in most materials at room temperature, there are always some ionized atoms and free electrons. These are available to neutralize ionized atoms.

[@alexdemoura9972]

aplaus for explanation of unstability of havier elements, many thx! 10:02 but what energy is released? i mean, it could not be that of strong force; even fissioned nucleons are still carriers of the same amount of strong force and are perfectly capable of fusion into havier elements again...

[@ThinAirElon]

you made my college physics course to go to dust ! Honestly i wasted 2 years and dint understand. After watching your video multiple time I am happy now

[@Yubel1100]

Curious are we sure that neutrons in the nucleus remain stable and dont just decay then the electron is immediately captured by a proton which would produce an neutrino which would annihilate with the antineutrino originially produced thus making it appear as if nothing changed.

[@ATSFVentaSpurNscaler]

This was an excellent primer video, but at its end you forgot to mention the Lawrence Livermore National Laboratory's recent fusion breakthrough using lasers. For the first time in human history, scientists achieved net energy gain from nuclear fusion without using a hydrogen bomb.

[@ArvinAsh]

We have achieved fusion using lasers before, the breakthrough appears to be that in the LLB experiment, there was net positive energy created. This, however, needs to be verified.

[@ATSFVentaSpurNscaler]

@@ArvinAsh Yes, thank you for clarifying that the breakthrough appears to be in the experiment’s net energy gain. To be sure as you’ve mentioned, independent verification remains essential for this (and, for that matter, every) scientific breakthrough.
